Example 1: state with react functions

constructor(props) {
super(props);
this.state = {
count: 0
};
}
render() {

<div>
<p>You clicked {this.state.count} times</p>
<button onClick={() => this.setState({ count: this.state.count + 1 })}>
Click me
</button>
</div>

Example 2: what is state in react
// State is essentially a global class variable
// that is modified when the component updates
class Clock extends React.Component {
constructor(props) {
super(props);
this.state = {date: new Date()};
}
render() {
return (
<div>
<h1>Hello, world!</h1>
<h2>It is {this.state.date.toLocaleTimeString()}.</h2>
</div>
);
}
}
